Partial offload of a container

I want to distribute the contents of a container (carried by a transporter) to different destinations, e.g. I have two red MUs and three green MUs in the container, and the red one must go to SingleProc named "RED" and the green ones to SingleProc named "GREEN". I have searched the Forum with the phrase "offload part of container" but could not find a solution. Can you please point me to previous answers or give ideas how to do this?
